OMEGA® finned strip heaters are extremely efficient and
dependable as a heat source for hundreds of industrial and
commercial applications. They are used for both forced
(mounted in a duct) and natural convection air heating
(mounted at the bottom of cabinet type ovens).
The finned strip heater’s basic design consists of a helically
wound resistance coil placed in a specially designed ceramic
insulator. The resistance coil is mechanically connected to
the screw terminal for positive connection. Stainless steel
rectangular tubing is used to house the heater assembly. All
remaining voids are filled with high purity magnesium oxide
to increase thermal conductivity and dielectric strength.
Nickel-plated steel fins (stainless steel optional) are mounted
to the rectangular tubing. The fins have been specially
designed to provide maximum surface contact for good heat

dissipation into the finned cross sections, thus resulting in
rapid heat transfer to the air.
OMEGA finned strip heaters are manufactured in a full line
of standard sizes, electrical ratings and terminations, or can
be made to your specifications.

Secondary Insulating Bushings
Secondary insulating ceramic bushings increase the effective space
between the heater and grounded surface for electrical clearance at high
voltages. They must be used on the mounting tabs when the finned
heater is connected with a direct line voltage above 300V.
When insulating bushings are required, a 13 x 16 (1⁄2 × 5⁄8")
slot is substituted for the standard slot size 8 x 13 mm
(5⁄16 × 1⁄2").
Insulating Bushing Assembly
Model Number: CERR-1001

CAUTION: When using secondary insulating bushings, the heater must be guarded to avoid any accidental contact. The guard
must be electrically isolated from the heater and must be properly grounded.
Ceramic Covers for Insulating
Screw Terminals
Igloo™ Ceramic Covers
Igloo ceramic terminal covers consist
of two individual ceramic parts. With
a tight-fitting cap and a solid base,
an Igloo cover will fully insulate any
standard 10-32 terminal lug used for
electrical wiring hookups.
Igloo covers can be assembled on all
channel strip and finned strip heaters
with Type T1 and Type T4 screw
terminals. Mica strip heaters with screw
terminals that have a minimum center
to center distance of 22 mm (
also be assembled with Igloo covers.
Three different types of Igloo bases are
available for your wiring convenience.
Double port in-line, double port 90°
and single port.
